Standard Wires 55629 Spark Plug Wire Set

Ignition Wire Set for Porsche 911

Standard Wires 55629 is a spark plug wire set for 1985-1989 Porsche 911 models. It uses a hi-gloss clear coat over a high-temperature silicone jacket to add abrasion resistance and thermal protection in demanding ignition environments.

• Fits 1985-1989 Porsche 911
• Patented clear-coat exterior with high-temp silicone jacket
• OE-type wire core design for low resistance and stable voltage delivery
• Improved abrasion resistance for engine bay durability
• Enhanced RFI suppression for cleaner ignition performance
• Standard Wires 55629 application-specific ignition wire set

Detailed Product Overview

Built for the Porsche 911 ignition system, this wire set is engineered to channel maximum voltage to the spark plugs while maintaining protection against severe heat. The core design follows OE-style construction options, including low-ohm, ferrite magnetic, wire-wound, silicone, or metallic configurations, depending on the application requirements. Standard Wires 55629 is a direct-fit ignition service part for 1985, 1986, 1987, 1988, and 1989 Porsche 911 models.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues It Can Address

• Misfires caused by worn or heat-damaged plug wires
• Voltage loss between the ignition coil and spark plugs
• Radio frequency interference affecting ignition performance
• Cracked insulation from abrasion or engine heat
• Rough idle or hesitation related to degraded wire conductivity

Installation Notes and Tips

Verify routing against the original wire layout before installation to maintain proper firing order and separation. Inspect boots, terminals, and spark plug condition during service, and replace any damaged ignition components at the same time. Confirm fitment for your specific 1985-1989 Porsche 911 before purchase.

Quality Assurance

Standard Wires uses a high-temperature silicone jacket and enhanced core construction to support consistent ignition performance and added protection in severe operating conditions.
